As the car descends in thefinal (oil o l" the conveyor, to the exit opening 7), the lug 13 on. thecasing above the door will contact with the latch 14-, pivoted upon thepin 14* in the upper portion of the car frame, releasing the bar 15allowing it to swing through the opening 7) onto the roller 17, erectedon the fame of the eonveyer 7. In the further descent of the car the bar15 will be drawn through the slot (1 of the easing, and descending uponthe rollers 17 and id. is brought to uprightposition where it is engagedwith the latch 1.4, which is held substantially in horizontal positionby the catch 1 t At this point the conveyor will traverse the chamber tothe entrance opening. Upon the release of the bar. the wargo ll will bemov ed onto the conveyer 7, where it will be conducted to the freightcar,for storage room.

Along the top and bottom members of the chamber are provided tubes 1 and1 respectively, each of which opens into the chamber. Connected withthese tubes are pipes leading from a cold. air supply and by means ofthem the cold air delivered from above and below, as indicated by thearrows, upon the moving crates. The air is thus thoroughly distrilmtedthrougl'iout the chamber and each carriage has all sides similarlypresented to the cool currents. Upon one side of the chamber, at themedian point an outlet tube 5, by which the cool air is exhausted. Inthis manner the produce may be thoroughly cooled before loading forshipment, thereby reducing the amount of ice required in transit. Or, ifit be desired to store said fruit, the same having been thoroughly anduniformly cooled throughout the boxes or crates in which it is packed,the keeping qualities of said fruit /\vill be greatly enhanced, and saidfruit will not require as large an amount of circulation of air in thestorage \voiild be necessary otherwise.

The rate of speed for moving the device will obviously be determined bythe kind and quality of the fruit or produce to be cooled and the timerequired for cooling same, and also by the time needed in makingtransfers through the intake and CXlt' opening, a lever, having aslotted end, pivoted to the casing, a lever having a slotted end,pivoted to the outer portion of said bracket, a stop pivoted to thefront end thereof and rising through the runway, a rear stop having atransverse pivot bar, adapted to operate in the slot of said bracket andforming a bearing for the slotted'ends of said levers, and means foroperating said levers to engage and disengage the stops.

2. The combination in a cooling device, of

a casing having an opening in the side thereof, a car movable verticallyin the easing, a runway leading to said opening, a bracket having avertical slottherein, secured to the casing beneath said opening, alever having a slotted end pivoted to the casing and extending withinthe casing wall, a lever having a slotted end,'pivoted to the outerportion of said bracket, a stop 1nember pivoted to the front end thereofand rising through the runway, a rear stop having a transverse pivotbar-adapted to reciprocate in the slot of said bracket and forming abearing for the slotted ends of said levers, means upon the car adaptedto engage the first mentioned lever for operating said stops, and means.for automatically restoring the stops to initial osition.

In testimony whereof I a x my signature in presence of two Witnesses.
